🔍 What Is a Robots.txt Generator?
A Robots.txt Generator is a tool that helps you create a robots.txt file — a simple text file placed in your website's root directory that tells search engine crawlers which pages or sections they are allowed or not allowed to crawl. Instead of memorizing the syntax, you use a visual interface to select user-agents, add allow/disallow rules, specify sitemaps, and set crawl delays.
◆ This tool processes everything entirely in your browser — no data is ever sent to any server. Your configuration stays private and secure.

⚠️ Important Notes & Limitations
🔹 Not a security tool: Robots.txt is a courtesy standard, not a security mechanism. Malicious bots can ignore it. Never use it to hide sensitive data — use authentication for that.
🔹 Must be at root: The robots.txt file must be placed at the root of your domain: https://yoursite.com/robots.txt. It won't work in subdirectories.
🔹 Case sensitivity: The paths you specify are case-sensitive. /Admin/ and /admin/ are different paths.
🔹 Crawl delay support: Googlebot ignores crawl delay in robots.txt (use Google Search Console instead). Bing and other crawlers generally honor it.
❓ Frequently Asked Questions
A robots.txt file is a plain text file placed in the root of your website that tells search engine crawlers which pages they can and cannot crawl. It's used to prevent indexing of admin pages, duplicate content, and other pages that shouldn't appear in search results. It also helps you point crawlers to your sitemap for efficient discovery of your important pages.
Absolutely 100% safe. This tool processes everything in your browser using vanilla JavaScript. No data is ever sent to any server, stored, or shared with third parties. Your configuration stays on your device.
No — robots.txt is not a security tool. It's a voluntary standard that ethical crawlers follow, but malicious bots can ignore it entirely. Never put sensitive data on publicly accessible URLs and rely only on robots.txt to hide it. Use password protection, authentication, or IP restrictions for real security.
Disallow tells crawlers not to access a specific path. Allow tells them they can access a path — useful when you've disallowed a parent directory but want to allow a specific sub-path. Allow rules take precedence over Disallow when the paths match in length.
